| Research Abstract |
Vitamin E(Tocopherol ; Toc) is a fat-soluble and Vitamin E is metabolized with the liver. It has not been clarified before that Toc is metabolized in the extrahepatic tissue. The aim of this study was to determine if Toc isoforms were metabolized in extrahepatic tissue. It as result, Toc is metabolized via cytochrome P450-dependent pathway in the intestine during absorption. And it was clarified an excessive amount of α-Toc promotes metabolizing γ-Toc. In addition, it is suggest that dietary sesame seed inhibits not only γ-Toc metabolism to γ-CEHC but also α-Toc metabolism to α-CEHC in rats.
